This brought me back to those historical kdramas I used to watch around 2016. Those ones that you get invested in the characters and story and it flows so well.
I think it has an interesting angle on war during this era from perspectives of royalty, invaders, civilians, women, scholars, soldiers. It can get so tense on some episodes and I love it lol. The fight and flight scenes are gripping to watch in themselves (forget the romance for a second).
The ML is such a cool guy and he knows many things with an unclear backstory (I guess we will see in season 2). FL comes off a bit arrogant to begin with but when the war comes she really proves herself, I guess she just needs to mature in terms of love and romance. Either way they have great chemistry. I would definitely recommend this drama for the action and the romance and everything in between.
